淋巴细胞是直接参与机体免疫的重要效应细胞。淋巴细胞膜上存在多种离子通道 ,其中主要为电压依赖性钾通道。目前 ,对鼠淋巴细胞该通道的研究较深入 ,它可分为ｎ、ｎ’和ｌ型三种亚型 ,但对人外周血淋巴细胞膜上钾通道的研究较少。国内尚未见这方面的报道。本文采用膜片钳技术? Lymphocytes are directly involved in the body’s immune effector cells. There are many kinds of ion channels on the membrane of lymphocytes, mainly voltage-dependent potassium channel. At present, the study on the channel of murine lymphocytes is more in-depth. It can be divided into three subtypes, n, n ’and l, but few studies on the potassium channel in human peripheral blood lymphocytes. Domestic yet to see this report. This paper uses patch clamp technology?
